Post-apocalyptic dramas haven?t exactly been in short supply in recent years, but The Last Ship docked at TNT last summer with a slightly unique spin on the genre. The show focused on the crew of a U.S. Navy destroyer who unexpectedly find themselves in the position of having to save the world from a global viral pandemic. Having wrapped the first season with a whopper of a cliffhanger, the crew of the U.S.S. Nathan James returns on Sunday. They'll discover that having a cure for the virus doesn?t mean that their mission is at an end.??
